HOSE-- NOZZ LE.

SPECIFICATION forming part of Letters Patent No. 240,833, dated May a, 1881.

Application filed October 27, 1880. (No model.)

To all whom it may concern Be it known that we, SAMUEL W. MARTIN and GHARLEs H. PAXsoN, of Springfield, iu the county of (Jlarke and State of Ohio, have invented certain Improvements in Hose-Nozzles, of which the following is a specification. -The object of this invention is to produce for domestic use an exceedingly cheap and convenient nozzle, adapted, like those in general use, to produce a jet or spray at will, as occasion may require.

The invention consists in a cast-iron nozzle provided with lugs which retain a removable rose or sprinkler in place thereon, and coated in the interior with japan, asphalt-varnish, porcelain-enamel, or other coating capable of being applied in a fluid condition, to render the surface smooth and facilitate the flow of the water.

Hitherto it has been customary to cast nozzles of brass and finish them at a considerable expense, connecting them to the hose by means of a corrugated neck, and providing them at the forward end with a threaded neck .to re- 2 5 ceive a mouth-piece or a rose, according to the requirements of the occasion. Our construction is far less expensive, avoids the difficultiesincident to the frequent mutilation of the screw-thread, and gives a freer vent to the water.

Figure 1 represents a side view of our improved nozzle, with the rose disconnected and shown in section; Fig. 2, a side view of the front end of the nozzle, showing the lugs 3 5 thereon; Fig. 3, an inside face view of the rose or sprinkler 5 Fig. 4, an end view of the nozzle;

Fig. 5, a side view of the nozzle, with the rose secured thereon, the latter being shown partly in section, to illustrate the manner in which it is fastened.

A represents the body of the nozzle, cast complete in one piece, with the corrugated neck 0b at the rear end to enter the hose, and with the two side lugs b on the forward end.

5 The hole or opening through the end of the body is made of such size as to produce a jet of the size ordinarily required, thus avoiding the necessity of using the ordinary removable tip on the end. The rear sides of the lugs 12 are inclined or beveled, as shown, and the nozzle provided in rear of the ln gs with a collar or shoulder, c, and a washer, d, of rubber or other elastic material seated againstthe shoulder.

The rose or sprinkler B is made of substantially the ordinary form but instead of having a screw-thread tapped in its rear side, as usual, it is provided with an oblong opening, 6, to admit the end of the nozzle and the lugs thereon, and with internal inclined shoulders f, which pass behind the lugs of the nozzle when the rose is rotated thereon, as shown in Fig. 5, so as to hold the rose securely upon the nozzle, and tightly against the elastic packing. The packing serves not only to produce a water-tight joint between the nozzle and the rose, but also to prevent the latter from working loose.

In order to secure the full effect of the water-pressure it is important that the interior of the nozzle be smooth and even, so that the wa- 7o ter may pass through steadily and without interruption. This end we secure by coating the interior of the nozzle with japan, asphalt-varnish, porcelain-enamel, or other suitable substance or material capable of being applied in a fluid condition. The coating, being thus applied in liquid or fluid condition, fills all the depressions and covers all the inequalities, and presents, when hard, a perfectly smooth, unbroken surface. The nozzle, being made of iron, is also coated on the outside with mate rial the same as, or other than, that used for the interior, to prevent oxidation.

The lugs on the forward end of the nozzle, unlike the ordinary screw-thread, are not liable 8 5 to injury when the nozzle is thrown down or dragged about upon the pavement, as so frequent-ly happens in practice.

The nozzle constructed as above can be man ufactured very cheaply. In durability it is the 0 equal of those made in the ordinary manner, and in convenience of adjustment it is their superior.

We are aware that a metalpipe has been provided with a glass lining secured in place 5 by means of an intermediate filling.

We are also aware that it has been proposed to preserve wood and also gas and other metal pipes by first coating them with litharge, Venetian red, and pine-varnish, and then apply- I00 ing thereon a coating of composite enamel.

Our invention relates especially and peculiarly to hose-nozzles, and its primary object is to render the interior of the same perfectly smooth, so that the water may pass through the same steadily Without undue friction, and without being diverted from its straight course, it being a well-known fact that the force of the water and the distance to which the stream can be thrown are greatly diminished by any irregularity or roughness in the surface of the nozzle. In constructing our nozzle the enamel is applied directly to, and is retained firmly by, the rough surface of the cast metal, and is applied with special reference to its producing a smooth and true inner surface. Of course the enamel serves incidentally to protect the metal from oxidation; but this is of secondary importance.

What we claim is- 1. As a new article of manufacture, a tapering cast-metal hose-nozzle having a smooth 2o interior surface produced by a coating of enamel, or its described equivalent, applied (lirect-ly to the surface of the metal.

2. The combination of the nozzle or jet-pipe having the lugs thereon and the rose or sprink- 25 ler connected and arranged to interlock with the lugs, as shown.

, 3. The combination of the cast-metal nozzle having the lugs thereon, the elastic washer applied thereto, and the removable rose "seated 0 against the packing and secured by the lugs.
